I have Win7 Pro 64bit running Office 2007. I am an IT trainer and train end users on Office. I understand the basics of home user accounts and pst files.

In Outlook I had set up 3 accounts: - Barry’s mail, Marta’s mail, Kevin’s mail.

I was having issues with my Barry’s mail account as I could not set it to the default, plus outlook was not always able to connect to this account.

So I decided to backup/save my outlook.pst file and delete all of Office 2007 and start again.

I used the Control Panel / Programs and Features / MS Office 2007 / Uninstall procedure but this does NOT remove all the files on the system so I also manually removed the Outlook files that were left on the system.

I reinstalled Office 2007, did not put the old pst file back in place and started Outlook but it kept asking for the pst file (so I obviously had been unsuccessful in hoping for a fresh install).

I put the old pst file back in place and Outlook opened OK however where the 3 personal accounts were (Barry, Marta, Kevin) there are now 3 unnamed folders that also show in the account settings as unnamed accounts. I deleted these accounts but they reappear when I reopen Outlook.
